Identify the characteristics of a 'rival' good: A good is considered rival if one person's consumption of the good reduces the amount available for others.
Identify the characteristics of a 'non-rival' good: A good is non-rival if one person's consumption does not affect the availability of the good for others.
Identify the characteristics of a 'non-excludable' good: A good is non-excludable if it is not possible to prevent people from using it.
Consider a slice of pizza: When one person eats a slice, it is no longer available for others, indicating it is a rival good.
Determine if a slice of pizza is excludable: Since you can prevent others from eating it by not sharing, it is excludable, thus not fitting the non-excludable category.
